About air photos of B.C.
The provincial government has over 2.5 million air photos of British Columbia, dating back to 1936. To date, about 500,000 air photos have been scanned from film into digital format. The B.C. Government is continuing to convert historical air photos into a digital format so they can be accessed online. Aerial photographs are exposed at various altitudes using a variety of conventional and digital cameras, providing overlapping (stereo) coverage of the ground.
Most areas of British Columbia are covered by air photos that are less than ten years old, with large areas covered by medium scale photography.
Black and white aerial photography is available for all of B.C. at a variety of scales and, in some areas, dating back more than fifty years. Colour aerial photography is becoming increasingly available for more areas of the province.

Technical information
Specification guidelines
Aerial photography produced with any government funds must meet B.C. Government specifications:
Scales
A photographic scale indicates that one unit of distance on an air photo is a representation of a specific number of the same units of actual ground distance. Scales can be expressed as a:
- Unit equivalent (e.g. 1 cm = 200 m)
- Representative fraction (e.g. 1/20,000)
- Ratio (e.g. 1:20,000)
The scale range for block aerial photography is 1:10,000 to 1:70,000. The scale range of site-specific aerial photography is from 1:2,500 to 1:50,000. Not all scales are available for all areas.
A large scale photo (e.g. 1:2,500) means that ground features appear larger and more detailed. The area of ground coverage depicted on a large scale photo is less than at a smaller scale.
A small scale photo (e.g. 1:70,000) means that ground features appear smaller and less detailed. The area of ground coverage depicted on a small scale photo is more than at a larger scale.
The scale of the photography varies, depending on the height of the aircraft above the ground and the focal length of the camera used. Over mountainous terrain, the scale can vary considerably within each photo.
